The Zhentarim in Londolond have a notable presence, but do not operate openly. So far, the party is aware of the Red Pulpit tavern as a location where they can get in touch with the Boss and his second-in-command, Fennik. The Boss's name has not yet been discovered, and he does not share it freely.
So far, two jobs have been performed by the party
- acquire the heart of a Sylvan and return it to the Boss within a day
- poison an innkeeper (the Merry Carriage incident)
... and one favor has been repaid:
- the Zhentarim have helped supply Neither Nor with extra quicksilver.
Fennik had a subsequent request for the party - to steal the Augur of Onimat from the Silver Twilight Lodge, but was slain shortly afterwards. The Boss has presumably survived, but has gone into hiding.
